【Abstract】 To simulate 1000 kV AC power transmission system accurately, a series of models, including the element models of 1000 kV transmission line with impedance angle reaching to 88.5?and corresponding component models such as capacitive voltage transformer (CVT), transformer ampere (TA), parallel reactor, etc. are developed by dynamic simulation department of CEPRI, based on parameters of the UHV pilot project from Southeast Shanxi via Nanyang in Henan province to Jingmen in Hubei province. The dynamic simulation system for 1000 kV AC power transmission project can be used to the research on characteristics of transient processes and provides test conditions for design and type selection of relay protection .更多还原
